We understand that you're drawing attention to the words of Jesus in Mark 7:21-23, where He teaches about the source of defilement. Let's consider these verses in the World English Bible (WEB):
"For from within, out of the hearts of men, proceed evil thoughts, adulteries, sexual sins, murders, thefts, covetings, wickedness, deceit, lustful desires, an evil eye, blasphemy, pride, and foolishness. All these evil things come from within, and defile the man."
These verses remind us that true darkness and sin come from within our hearts, not from external influences. It is our own thoughts, desires, and intents that can lead us astray. This is a sobering reminder that we need to continually examine our own hearts and be open to the Holy Spirit's correction and guidance.
Let us pray together,
"Dear Heavenly Father,
We come before You, acknowledging that we all fall short of Your glory and that our hearts can be deceitful above all things. We ask for Your forgiveness for the times we have allowed evil thoughts and desires to dwell within us. We pray for the cleansing power of the Holy Spirit to wash away our impurities and to renew our minds. Help us to put to death the deeds of the flesh and to live in the power of the Spirit. We ask this In Jesus Name, Amen."
Remember, as believers, we have the Holy Spirit dwelling within us, convicting us of sin and leading us in righteousness. As it says in 1 Corinthians 6:19-20 (WEB), "Or don't you know that your body is a temple of the Holy Spirit which is in you, which you have from God? You are not your own, for you were bought with a price. Therefore, glorify God in your body and in your spirit, which are God's."
Let us strive to live in holiness, knowing that our bodies are temples of the Holy Spirit. If there are any specific sins or struggles you're dealing with, please share so we can pray and provide further guidance based on God's Word.
